Abstract

Developing skin-like ionic sensing materials is highly desirable for skin bioelectronics for long-term health monitoring, which is challenging to realize by using biocompatible natural polymer-based biogels. Herein, we engineer a robust natural protein-based ionic biogel with skin-like combinational properties involving stretchability, softness, durability, ionic conductivity, and environmental adaptability, which is enabled by a synergistic effect of biomimetic nanofibrous structures as well as solvent and ionic enhancement. The skin-like mechanics and functionality of the as-designed natural protein-based biogels suggest their further applications in advanced skin sensors for long-term and high-fidelity physiological monitoring. As a proof of concept, we successfully demonstrate high-quality continuous monitoring of electrocardiograms for 1 week under daily life conditions using such natural protein-based skin-like ionic biogels.

期刊介绍： ACS Materials Letters is a journal that publishes high-quality and urgent papers at the forefront of fundamental and applied research in the field of materials science. It aims to bridge the gap between materials and other disciplines such as chemistry, engineering, and biology. The journal encourages multidisciplinary and innovative research that addresses global challenges. Papers submitted to ACS Materials Letters should clearly demonstrate the need for rapid disclosure of key results. The journal is interested in various areas including the design, synthesis, characterization, and evaluation of emerging materials, understanding the relationships between structure, property, and performance, as well as developing materials for applications in energy, environment, biomedical, electronics, and catalysis. The journal has a 2-year impact factor of 11.4 and is dedicated to publishing transformative materials research with fast processing times. The editors and staff of ACS Materials Letters actively participate in major scientific conferences and engage closely with readers and authors. The journal also maintains an active presence on social media to provide authors with greater visibility.
